People who fake their results are not advancing knowledge. In the case of the Alzheimer’s paper, it held back knowledge for a very long time.

Beyond that though, these are cases of blatant fraud that steals money from the taxpayer.

That's more on the field than the fraud, I fear. Papers can make all kinds of serious errors without any fraud, just due to ignorance, incompetence, or error.

If one fraudulent actor is massively setting back a field then there is too much trust in published results.
